      drm: clean up unused kerneldoc in drm_lease.c · 676f11b5
      Desmond Cheong Zhi Xi authored
      The kerneldoc in drm_lease.c is unused because none of the functions
      are driver interfaces as the symbols are not exported.
      
      Since they aren't used and much of the existing comments don't provide
      any insights (e.g. they just repeat the function name or list out the
      function parameters), they should be removed to make them easier to
      maintain and to make useful info more obvious.
      
      As a note, many of the comments mention whether idr_mutex should be
      held, but these are mostly redundant in cases where the function
      contains lockdep assertions or grabs the mutex.
      
      To simplify review, here's the reasoning behind each update.
      
      drm_lease_owner:
      function name is self-descriptive
      
      _drm_find_lessee:
      function name is self-descriptive
      
      _drm_lease_held_master:
      function name and signature are self-descriptive
      
      _drm_has_leased:
      kerneldoc is summarized into a comment because the function name could
      be interpreted ambiguously (check if the object has been leased VS
      check if the master has a lease on the object)
      
      _drm_lease_held:
      Retain the idr_mutex comment because the function does not directly
      grab the mutex or use a lockdep assertion.
      Otherwise, the function name is self-descriptive.
      
      drm_lease_held:
      function name is self-descriptive
      
      drm_lease_filter_crtcs:
      Kerneldoc is summarized into a comment because the function name could
      be interpreted ambiguously (filter leases based on crtcs mask VS
      filter crtcs mask based on leases)
      
      drm_lease_create:
      Kerneldoc removed.
      Useful function details such as atomic leasing are retained.
      Errno interpretations are useful and retained.
      
      drm_lease_destroy:
      function name is self-descriptive. Additional information is also
      removed as they're already present as comments inside the function.
      
      _drm_lease_revoke:
      function name is self-descriptive
      
      drm_lease_revoke:
      function name is self-descriptive
      
      drm_mode_create_lease_ioctl:
      Kerneldoc removed, but useful function details retained.
      
      drm_mode_list_lessees_ioctl:
      function name is self-descriptive. Additional details restate what the
      code does.
      
      drm_mode_get_lease_ioctl:
      Function summary retained to clarify that it's the leased objects that
      are returned, not the lease structure.
      
      drm_mode_revoke_lease_ioctl:
      Kerneldoc removed, but useful function details retained.

      Dave Airlie authored
      An early pull for v5.15 (there'll be more coming in a week or two),
      consisting of the drm/scheduler conversion and a couple other small
      series that one was based one.  Mostly sending this now because IIUC
      danvet wanted it in drm-next so he could rebase on it.  (Daniel, if
      you disagree then speak up, and I'll instead include this in the main
      pull request once that is ready.)
      
      This also has a core patch to drop drm_gem_object_put_locked() now
      that the last use of it is removed.
